Gremlins, they happen to everyone.

Thanks for that John and you also Rob. Sounds like the solution for the last worrisome issue on mine.

Are the adjustments made with tuneecu or mechanical adjustments to the TPS and ISCV while monitoring the voltage readings in the datastream?

Let's face it - our @Claviger likes hunting the little chaps. I think he lures them into a sense of false security before pouncing. A bit mean really.

He is a hell of a lot better at it than me.

Diagnostics screen in TuneECU, double click the ISCV reset and follow the instructions, just replace the .60 with .63 or .64 and the .72 with .75 or .76.

Good luck!

Thanks again Rob and John! Got rid of about 60percent of the stuttering by removing the secondary throttle plates. Thought the base tune I am running had them at 100 percent but it turned out they were still in play at low tps.



As John mentions, that brief lean swing when first cracking the throttle is a dead give away to what's going on. It manifests as a jerk or stutter, for those without a wideband. For those with a waidebamd it'll be a brief lean spike that no amount of tuning will correct.

Haha, I don't use one :0. I do it the hard way, small adjustments while it's running.

Ya gotta use one on the RIIIT Rob . They don't have individual readings on tuneecu for each cylinder. Ain't no other way to balance them.

Unless I am completely missing something which is always possible.
